of the shaft. This opening leads outwardly through the sides of the shaft just below the bearing 17. The lower end of this cable is fastened by an eye bolt 41 to the spider.

In this manner when the cable is wound upon the drum the spider will be lifted by the eye bolt 41 and raised from the water.

-It is' to be noted further that rotation of the spider may continue during the raising operation without tangling the cable, or causing it to be wrapped around the driv- The mechanically operating means for rotating the Windlass consists of a bevel clutch gear 42 which is mounted upon a sliding shaft 43. This shaft is "xupported within a frame 44 and may be tinue to rotate upon the shaft and the cable wound up as the propeller continues to rotate. I

In operation, the propeller, including the spider, bladesand float, are lowered into the water. lhe float is of a size to buoyantly support the spider and permit the blades to lie substantially in the horizontal path of travel of the waves,

' strike the blades they will be swung downwardly until they encounter the stops 24 and will then cause the rotation of the float and the squared shaft 16, upon which the float is mounted. This rotation will impart motion to the driving gear 25 and will, in

.turn, drive the gear 26 and the shaft 27.

In case the sea becomes exceptionally rough and itis thought advisable to discontinue operations of the motor, the propellermay be raised. from the water by shifting the clutch gear 42 into mesh with the driving gear .25 and the bevel gear 36. This will cause the Windlass to be rotated by the 36 with which the winding gear As the wavesgear 35 and will wind the calcite As the cable is wound up, the propeller will, of

course, be elevated and brought clear of the water.

It will thus be seen that thewave motor here disclosed is simple in its construction, not liable to get out of order, and may be inexpensively made.

While I have snown struction of my wave motor as own to the preferred conme, it will be understood. that, various changes in the combination, construction and arrangement of parts may be made by those skilled in the art without departing from the spirit of my invention.

'f Iclaimz i 1; A wave motor comprising a frame, a shaft rotatably mounted vertically on the fratne, a float slidingly and nonrotatably mounted on the shaft, a propeller spider fixed upon the float, a series of hingedpropeller blades depending from the spider radially to the shaft and free to swing one way, and stops to hold the blades from swinging the other way beyond a vertical plane.

2. A wave motor, comprising a frame, a

central ve'rtical shaft rotatably secured by said frame, a propeller adapted to rotate With said; shaft, means for buoyantly supporting said propeller upon the waves of a body of water, a transmission operated by the action of the water against the propeller, and means whereby said propellermay be raised from the water undtjhjitsx own power ofi'otation.

3. A wave'aniotor, comprising a. frame, a 1

vertical shaft mounted thereupon, a bnoyant drum slidably positioned upon the shaft and adapted to rotate therewith, a pro peller spider secured at the top of, said buoyant drum and having arms extending .radially therefrom, a series of hinged P peller blades vertically hung from said spider arms, means whereby the force of waves against the blades: will cause the drum and shaft to rotate, and-means whereby ro tation of said shaft may be used to cause the propeller to be raised from the water.

4 In testimony whereof I have signedv my name to this specification.
